No. 908,015. Specification of Letters Patent.

To all whom it may concern:

Be it known that I, FREDERICK LEWIS KUHN, a citizen of the UnitedStates, residing at Fitchburg, in the county of Worcester and State ofMassachusetts, have invented a new and useful Lamp Attachment, of whichthe following is a specification.

The invention relates to wick, locks for burners of lamps, stoves andthe like, and hasfor its object to provide a device of this class whichcan be applied to any of the ordinary types of burners without affectingor necesholder and preferably threaded therein for longitudinaladjustment, is a rod or pin 8 having a thumb head 9 to facilitateadjustment to cause the extremity of the rod to engage the spindle 2 andthus clamp the latter in the seat. The lock may, also, be provided witha foot 10 which as illustrated, may rest upon the body of the lamp orstove or other object in connection with which the lock is employed.

In the modified embodiment illustrated in Fig. 3, the construction abovedescribed is sitating any change in the constructlon of duplicated,(except in so far as the foot 10 is the burner itself, or of the wickraiser, or its concerned, the latter being omitted from this T form),and the two locks are connected by an intermediate rod 11 formedintegral with or rigidly secured to the enlargements or heads in whichthe spindle engaging seats are located. Thus, in the modificationreferred to the body of the lock 4 terminates in an enlargement or head6 having a seat or notch 7 while the olamprod 8 indicated in dottedlines, carries the thumb head 9. Obviously the use of a foot as shown inthe form of the spindle, or any other part of the structure;

and, also, to provide a device of this class which, with slightmodification, can be applied either to one or more wick raiser spin-With these and otherobjects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts, hereinafter fully described, illustrated inthe accompanying drawings, and particularly invention illustrated inFig. 1 is not necespointed out in the appended claims, it belng sary inthe modification illustrated in Fig. 3 understood that various changesin the form, and, in fact, is not indispensable even in the simplerorsingle form shown in Fig. 1, for the reason that the weight of thelock is sufiicient to prevent the turning of the wick raiser by theswelling of the wick due to the feed of the illuminating fluid, theobject of the look, as in similar devices of this type, being to preventthe creeping of the wick due to the expansion under conditions of use,and thus to prevent the flame at the burner tip from increasing after ithas been set to the desired height. To readjust the wick it is onlynecessary to loosen the clamp, or unscrew the rod, and thus free thewick raiser spindle, andwhen the desired adjustment has been reached,the tightening of the clamp will secure the parts against accidentaldisplacement.

I claim:

1. As an article of manufacture a wick lock comprising an elongated bodyhaving a seat extending thereinto adjacent one end, and a foot deendingfrom the body, said body and foot eing formed in a single piece,there being a longitudinally screw threaded bore within the body, aspindle insertible into the seat, and a threaded clamping pinenlargement or head 6 in which is formed a adjustably mounted within thebore for denotch or seat 7 to receive the wick raiser, and taohablybinding the inserted spindle against fitted in the bore of the bodyportion of the one wall of the seat.

proportions, size and minor details of the structure may be made withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the accompanying drawings :Figure 1 is a view of the wick lockapplied in the operative position to an ordinary type of wick raiser.Fig. 2 is a longitudinal sectional view of the lock. Fig. 3 is aperspective view showing a modified form of the lock adapted for use inconnection with a plurality of wick raiser spindles.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

In the drawings there is indicated at 1 an ordinary form of burnerhaving a wick raiser spindle 2 to which is attached the usual t umbpiece 3, and clamped to the spindle Is In the embodiment illustrated,the lock consists essentially of an elongated body having means forengagement with the spindle of the wick raiser, and a preferred form isShown in Fig. 2, wherein the body of the lock is tubular, being bored asat 5 and having an 2. The combination With spindle; of a lock com a seatextending there for the reception of the spindle, a threaded pin adjustably mounted Within the body for detachably clamping said spindleupon one Wall of the seat, and an integral foot depending from the body.

In testimony that I claim the foregoing as my own, I have heretoafl'lxed my slgnature 10 111 the presence of two witnesses.
